APPARATUS FOR PiLlNG METAL BARS.

5PEGIFICATION forming part of Letters Patent No. 546,159, dated September 10, 1895.

Application filed May 9, 1895- $erial No. 548,639 (No model.)

To all 10700122 it; may concern:

Be it known that I, JULIAN KENNEDY, of PltlSbllifZ, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Apparatus for Piling Metal Bars, of which the following is a full, clear, and exact description, reference be ing had to the accompanying drawings, forming part of this specification, in which- Figure 1 shows my improved apparatus in side elevation. Fig. 2 is an end elevation thereof.

The purpose of my invention is to provide means for receiving and piling metal bars or plates as they are delivered from the rolls of a rolling-mill, superposing them one upon another, so that they shall be in proper position for subsequenthandling, and that by reason of their being piled the air shall be excluded from their surfaces while cooling and oxidation thereby prevented.

In the drawings, 2 represents the finishing rolls of a mill for rolling metal plates or bars, from which the finished product is delivered in the direction of the arrow A. In front of said rolls, and in line therewith, is a receiver which is set within a frame composed of a series of upright guide-posts 3 3, arranged in two parallel lines, so as to afford between them a space within which the receiver can move vertically. At the base of said space, and extending lengthwise thereof, is the receiver, having a horizontal base or beam 4, faced on top with a removable cap 5, and having at each side vertical side plates l.

The base is rendered vertically movable by suitable lifting mechanism, which I show as consisting of a pair of hydraulic lifting-cyl inders 6 7, equality of whose motion is secured by bell-crank levers 8 8, connected with the base by links 9, and connected with each other by a rod 10. At the end of the base 4 is a stop-piece 11, which prevents the longitudinal passage of the metal plates beyond the end of the apparatus.

The operation is as follows: The movable receiver is raised until its base is opposite to and on a level with the rollpass, as shown in Fig. 1, and then as the metal plate is delivered from the rolls it passes within the receiver and rests upon the base between the side plates, and if of sufficient length to extend to the end of the receiver it is stopped by the stop-piece 11. The receiver is then lowered until the top of the first plate orbar comes to the level of the roll-pass, a second plate or bar is then rolled and passes into the receiver, where it rests upon the first plate or bar, the receiver is again lowered, a third plate or bar is delivered upon the second, and so on the receiver is successively lowered until it has received a pile of metal plates or bars of the desired number. The receiver is then raised between the posts 3 until the bottom of the metal pile which it carries has passed above pivoted dogs or pawls 12 on the posts, which drop into position beneath the pile, and then the receiver is lowered, leaving the pile sup ported by the dogs, as shown at 13 in Fig. 2, whence they can be removed by a crane.

The apparatus thus affords convenient and simple means for piling the metal bars or plates in proper position relatively to each other, and by reason of such piling, labor is saved, oxidation of the metal is prevented, and generally improved results are secured. The use of the side plates 4' is desirable, because they serve to exclude air from the pile; but while they are claimed specifically by me, my invention, broadly considered, is not limited thereto.

Changes in many respects in the form and construction of the parts of the apparatus may be made without departure from my invention as defined in the claims, since \Vhat I claim is- 1. In apparatus for piling plates and bars, the combination with a pair of rolls, of a vertically movable receiver in front of the rolls and in line with a pass thereof, and means independent of the rolls for positively moving the receiver downwardly after each piece is delivered thereinto; substantially as described.

2. In apparatus for piling plates and bars, the combination with a pairof rolls, of a vertically movable receiver in front of the rolls and in line with a pass thereof, posts or guides between which the receiver moves, and means independent of the rolls for positively moving the receiver downwardly after each piece is delivered thereinto; substantially as described.

3. In apparatus for piling metal bars and plates, the combination with the rolls, of a vertically movable receiver set in front of the rolls, and adapted to receive the metal there from and to be moved successively downward as the metal is piled thereon, and an elevated support to which the pile may be delivered by elevation of the receiver; substantially as described.

4:. In apparatus for piling metal bars and plates, the combination with the rolls, of a vertically movable receiver set in front of the rolls, and adapted to receive the metal therefrom and to be moved successively downward as the metal is piled thereon, posts'or guides between which the receiver moves and dogs on the posts or guides constituting an elevated support for the pile; substantially as described.

In testimony whereof I have hereunto set my hand.
